+51 Hello, I am very confused on how to solve the following problem. I would be very grateful if someone could explain it to me.
"The units digit of a three-digit number is 6. What is the probability that the number is divisible by 6? Express your answer as a common fraction."
+36915 Every 5th multiple of 6 ends in '6'
from 100- 999 there are 900/6 = 150 multiples of 6 (is that right?) of which 1/5 end in 6 = 30
there are 10 x 9 = 90 numbers that end in '6' 30 out of 90 = 30/90 = 1/3 chance
